There i s a need to provide teachers with more explicit examples of reasoning opportunities for the classroom as most of the examples cited by the teachers were limited to students explaining and justifying their choices. Teachers should have in their repertoire of reasoning tasks, activities that require reasoning to occur because of the need to: adapt the known to the unknown transfer learning from one context to another, generalise, prove that something is true or false, compare and contrast related ideas and explain choices as recommended in the AC: M (ACARA, 2012) An ambiguous understanding of reasoning is likely to perpetuate a lack of definitive action in the classroom. There is a need to support teachers on t heir journey to understanding and implementing curricular change. Such support is in the interest of students' mathematical learning.
